3rd year Linguistics & Didactics enquiry (LMD)

[xXBHXx]

Hi everyone, I hope you're doing well. I'm posting here and expecting to get an answer to my question, which I address to the students who have chosen Linguistics in their 3rd year (LMD system) at Bouzareah university.I want to know a bit about some unexpected modules such as Statistics ( what are we going to study in it, is it advanced or just theoretical ?) ,and if possible the other strange ones like Philology ( some have told me it's taught in Arabic, is it the case ?). I would really appreciate any helpful information or other pieces of advice.Please don't ignore this post if you know something.Thank you
